In particular the invention relates to dehumidifier systems and dehumidifiers comprising such dehumidifier systems, the dehumidifier systems each comprising a closed regeneration loop for regenerating a rotary desiccant wheel using superheated steam; and uses of excess superheated steam generated during regeneration.
Description
Technical field
The present invention relates to a kind of for using the system of superheated steam dehumidification regeneration system runner and relating to one and include
For using the dehumidifier of the system of superheated steam dehumidification regeneration system runner.
Background technology
In many industrial treatment, it is desirable to dry air contacts chemicals or food are with such as at convection type dehumidifier
Interior manufacture dry.In order to produce dry air, conventional method is to make the air entered from surrounding pass through to inhale
Attached dehumidifier, thus removes excess water from the air entered.
Adsorption and dehumidification machine, such as desiccant dehumidifier, remove moisture from a certain amount of air therethrough.Should
The particular matter of the hydrone of the moisture being made up of absorption in air is made or is scribbled by the core processed
The adsorber rotor of described particular matter.
Owing to rotor adsorbs water, so for the absorbability recovering rotor, removing that adsorbed water becomes must
Want.In order to remove the dampness in rotor, rotor rotates over renewing zone, in renewing zone, with the sky of heating
The dry rotor of air dry.The regeneration air of warm moist is brought out, and rotor gets out adsorbed water molecule again.
This operation can be continuous print or progressively.
In recent years, the concern to the increase of process economics has been carried out in dehumidifier design improving,
In the middle of other key element, this improvement focuses on reusing of the energy content to warm moist regeneration air,
Rather than only regeneration air is emitted into air.
It is an object of the invention to be proposed to be used in the improvement system of dehumidification regeneration system runner, the wherein shape in superheated steam
The regeneration air of formula is for the other purpose processed in stream being associated with desiccant wheel.
US 3,183,649 describes a kind of dehumidification system, and it includes that desiccant wheel, desiccant wheel include: first
Device, it is by the adsorption section of supply gas supply to desiccant wheel；Second device, it is by superheated steam supply
Regenerator section to desiccant wheel；With the 3rd device, its by flushing gas supply to purge zone.
WO 2008/044932 describes a kind of dehumidification system, and it includes that zeolite desiccant wheel, zeolite dehumidifying turn
Wheel includes: first device, and it is by the adsorption section of supply gas supply to desiccant wheel；Second device, it will
Superheated steam supplies the regenerator section to desiccant wheel；With the 3rd device, its by flushing gas supply to purge zone,
Thus each in first, second, and third device includes ventilator or compressor.Basis in prior art
In inventive embodiment, superheated steam makes zeolite desiccant wheel circulate in the regenerative system of closed-loop path, therefore
Each regeneration cycle is utilized to produce ever-increasing excess steam.In order to remove excessive moisture,
Inventor's suggestion of WO2008/044932 makes unnecessary superheated steam through over-heat-exchanger to heat supply gas in advance
Body, supply gas expection will be dried in zeolite desiccant wheel.But, therefore maintain the temperature of superheated steam
Energy required for degree is lost from closed-loop regeneration loop.Fig. 1 illustrates the dehumidifier of prior art.
The advantage using the zeolite desiccant wheel with superheated steam is carried by the adsorption property of zeolite at high temperature
Supply.But, the regeneration of zeolite desiccant wheel is less effective, unless the vapor (steam) temperature more than 200 DEG C for
Regeneration zeolite desiccant wheel, because the absorbability of zeolite the most significantly falls back to the water of 5wt% absorption
Below.In order to superheated steam is heated to the running temperature of abundance, this increases energy expenditure, and this is for maintaining
Can be difficult for operating environment, and be probably significantly from the heat loss regenerating flow path.Separately
Outward, any supply gas that such high running temperature is also required to entering desiccant wheel is heated for making
Zeolite desiccant wheel is not cooled to below the effective running temperature of expection Steam Recovery.Therefore, use overheated
Steam is lost for the part energy advantage of the regeneration of zeolite desiccant wheel.
An aspect of of the present present invention produces many based on superheated steam by suggestion in the regenerative system of closed-loop path
Other purposes of remaining superheated steam improves the energy efficiency of the system of prior art.Another aspect of the present invention
It is to provide the dehumidification system for the improvement being used together with other desiccant wheel in addition to zeolite, preferably silicon
Glue and/or the desiccant wheel of activated bauxite.
Therefore, one aspect of the present invention relates to using closed-loop path regenerative system to carry out rebirth silica gel based on superheated steam
Desiccant wheel, wherein, the unnecessary superheated steam and the energy that produce during the regeneration of desiccant wheel are used for installing
Have the present invention dehumidification system environment in other need in the process of energy.Therefore, in desiccant wheel
The silica gel used or the superpower absorbability of water of activated bauxite dehumidizer under low-running-temperature can with so
The closed-loop path superheated steam of desiccant wheel reclaim the energy combining and obtaining from Regeneration Treatment increase.
